Will Ferrell does broad comedy better than anyone I can think of and, as you might expect, this send-up eschews the subtle — perhaps wisely, since even Billy Wilder did not really succeed with the more obliquely comic approach of The Private Life of Sherlock Holmes (1970). Both Ferrell and John C Reilly, with whom he has formed a solid screen partnership, go to town with their cut-glass English accents, but this has none of the sense of fun of Step Brothers (2008), and the whole enterprise labors under the weight of its historical setting, enlivened only by occasional moments of genuine mirth (including some knowing digs at Donald Trump), amid predictable turns by Rob Brydon and Ralph Fiennes.
